In an issue of Vanity Fair that hits newsstands Wednesday in New York and Los Angeles, Seth Mnookin spells out the claims of Lewis Perdue, the author of a novel published three years before "The Da Vinci Code" entitled "Daughter of God," the New York Times reported Wednesday.
Perdue believes that Brown copied large portions of the plot of his book, the article says.
After Perdue hired lawyers to threaten a copyright infringement suit against Random House, the publishing company that owns Doubleday, publisher of "The Da Vinci Code," Random House filed suit against Perdue in 2004 "seeking a declaratory judgment stating that no copyright infringement had taken place," Mnookin wrote.
Perdue lost that suit and an appeal earlier this year.
But Mnookin's article suggests that Perdue might have a valid case, if not a strong legal one. Mnookin compared the novels, and found that "The Da Vinci Code" "contained a plot, pacing and structure that were very similar to "Daughter of God."
